IMPROVEMEN`T`IN MCHINES FOR CUTTING S'PLITS.

The Schedule referred to in these Letters Patent and making pari: of the same.

To all whom it may conce/m:

Be it known that I EBENEZER KNlGHT, of Elizabeth, in the county of Harrison, in the State of Indistruction and arrangement of a machine for cutting splits for chair splits, hayv hoops, or other purposes, from the log in such a manner as to follow the grain of the timber, as near as practicable.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation,'referring to the annexed drawing, in which- Figure lis a side elevation, and

Figure 2 `is a transverse vert-ical section of my machine.

A represents the frame of my machine, having at each end a slide, B, which can bel moved up and down in grooves on the corner-posts of the frame. The log from which the splits are to be cut is held by means of a bolt or pin, a, at each end, said bolt passing through the slides and into the log. The log thus becomes, so to say, pivoted on these pins, so that it may be turned around to present any point of its surface to the out-ting instrument.

During the operation of cutting, the log is held stationary by means of a screw, b, passing through one of the slides B into the end of the log, which prevents it from turning.

Thel slides B B may be raised oy any suitable means so as to bring the log to the proper heightl for the operation of the cutting instrument.

In the upper part of the frame, on suitable ways or guides, moves a carriage, .0, back and forth, either by means of' hand-power or other' power, that may be applied to the same.

v Through the carriage C passes an upright slide, D, to the lower end of which the hed fl is secured. In front ofthe bit, to the slide, is also secured a g'uide,f,

which is provided with side-cutters e e, as shown.

These side-cutters may be made adiustable if so desired. Y

On the side of the slide D is pivoted a cani-lever, E, which bears against the upper side of the carriage, and by means of which the slide, hit, and cutters are raised up from the log. In a standard ou the carriage is pivoted a lever, G, which bears against the upper end of the slide E, and a' spring, H, (or weight,) attached to the other end of said lever, holds it down on the slide so as to press the bit into the log, and at the same time allow the bit to adjust itself to ,any inequalities of the log.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of the frame A, slides B B, pins a. a, and screw b, substantially as shown and described, and forthe purposes set forth.

2. The combination of the slide D with bit d guide j, cutters e e, and cam-lever E, substantially as
